Pioneer DEH-80PRS CD Receiver with 3-Way Active Crossover Network, Auto EQ, and Auto Time Alignment
Best for avid music lovers
A simple-looking single DIN head unit that hides outstanding internal components and incredible sound.
1 Pioneer DEH-80PRS Review
The Pioneer DEH-80PRS goes well beyond most single DIN head units in terms of component quality and audio clarity. It looks unimpressive at first glance, just like a sort of vintage car stereo from the 90s. But don’t let the first impact fool you.
A fully detachable face plate reveals both an SD card and CD slot – the latter a rare feature on most modern single DIN head units. But what makes it stand out is the quality of its audio.
An internal amp is easy to turn on and off as needed; it can power four speakers and has plenty of controls that let you equalize the sound and tune both treble and bass notes. That’s not it! You can also expect Bluetooth connectivity with your Android phone, easy music streaming from Spotify or Pandora, as well as hands-free calls.
Designed to help you create an ideal listening environment while you’re driving and impressing with its other features, this is by far the best single DIN head unit for all the music freaks around.

Best Single DIN Head Unit 2021 Buying Guide
1. Single DIN vs. double DIN head units
The size of a head unit, or car stereo as it is commonly called, is measured according to the German industry standards (or Deutsche Industrie Normen – DIN), which is typically either single or double DIN. The main difference between the two is the size, or to be more precise, the height of the unit.
- Single DIN head units: Are about 2 inches (5 centimeters) tall and 7 inches (18 centimeters) wide. These compact units typically come as factory standards on the smaller city cars and on most basic vehicle models.
- Double DIN head units: Are called this way because they are twice as high as the single DIN. These units are 4 inches (10 centimeters) tall, but their width remains unvaried, of 7 inches (18 centimeters). Double DIN units are typically installed on the larger cars and on most full-optional car models. Due to their larger size, the double DIN head units typically integrate more features and are easier to control, although this is not necessarily a rule.
Besides the two main types above, some car models come with non-standard stereos; most non-standard units are 1.5 DIN with a typical height of 3 inches (7.5 centimeters), although some units may have random sizes that respect no industry standard.
2. Types of single DIN head units
The single DIN car stereos come in various types, but the following four are the most popular.
- Single DIN CD player: Perhaps the old-school model in the modern world, these head units feature a CD player but also auxiliary and USB inputs for playing mp3’s and a radio tuner. They can have analog or digital controls but rarely feature a touchscreen.
- Single DIN DVD player: Is the upgraded version of the CD player style and can play both CDs and DVDs. These head units typically have touchscreen audio adjustments and a fold-out display that allows watching video content. Like the CD players, they also have aux and USB inputs, a radio tuner, and most of them allow for smartphone integration and Bluetooth connectivity.
- Single DIN digital media player: Don’t accept CDs or DVDs but often integrate with streaming music services. These head units are ideal for those who mainly listen to music from smartphones or digital music players.
- Single DIN navigation: Can be any of the types above but also has a built-in GPS navigation system you can use instead of your smartphone when traveling.
3. Single DIN head units power
A powerful single DIN head unit with a good built-in RCA and amp line outputs will provide a great sound quality without requiring an additional amplifier. This is convenient when you want to enhance your car’s audio system without breaking the bank, but also to get more accurate sounds when building a bespoke car audio system.
Two values to check when assessing the unit’s power are the peak output and the root-mean-square (RMS).
- The peak power represents the total (or highest) value the waveform can reach, and most single DIN head units have a peak power of around 50 watts per channel.
- The RMS power represents the effective power of the sound and typically varies between 14 and 18 watts.
4. Sound quality
The sound quality varies greatly between the various types of single DIN head units. To create a quality audio system, it is recommended to invest in a car stereo with at least three RCA outputs for the front speakers, rear speakers, and a dedicated subwoofer output, and a high and low pass filter designed to boost the subwoofer’s output.
Besides these, you can also enhance the sound quality with the help of precision sound controls.
Precision sound controls
Precision sound controls allow you to adjust the head unit’s output for treble, midrange, and bass sound to match the audio with your car’s acoustic. If you want to have total control over the sound effects in your car, also consider the following features.
- Parametric equalizer: Allows you to set the sound intensity in decibels and the bandwidth at which a given frequency is boost or cut. These equalizers offer complete control of the acoustic balance of your system.
- Digital time correction: Is designed to compensate for the placement inaccuracies of the speakers by delaying the signal of the closest speaker to ensure all sound arrives at your ears at the same time, enhancing the accuracy of the acoustic image.
- Digital signal processor: Combines the feature of an equalizer with the adjustable listening positions of the sound field, enhancing the quality of the sound. These processors come as built-in units on the high-end single DIN head units or can be added to the standard car stereos.
5. Audio sources
The best single DIN head units can play audio from different sources, including CDs, DVDs, and media players. Some mechless head units allow playing music from USB drives or SD cards alone, and some even come with internal hard drives which can store your media files.
If you also like to listen to radio every now and then, check if the head unit you want comes with a radio tuner. Most car stereos come with basic AM/FM radio, but the most technological units also allow you to access the HD and satellite radio.
6. Bluetooth connectivity
Bluetooth connectivity goes beyond the possibility to play media from your smartphone. Most single DIN head units with integrated Bluetooth connectivity allow for hands-free calling by connecting to a microphone which either comes as a factory standard or can be installed separately.
7. App and smartphone integration
Most single DIN head units allow for app and smartphone integration, but you should check the unit you want is compatible with your device or desired app.
iPhone users should look for the specific Made with iPhone badge on the head unit to ensure the USB port matches their device. New Apple devices using the Lightning connector also require a dedicated USB port.
Android devices and most other systems are easier to connect via the standard auxiliary input or a standard USB port.
The best single DIN head units allow for streaming app integration; this means you will be able to play and control media from your preferred streaming apps like Pandora, Spotify, or iHeart Radio
Some units also come with dedicated apps which allow controlling the system remotely or access dedicated media libraries.
8. Other important features
- Preamp output: Is important if you want to build a state-of-the-art car audio system, as it allows you to connect an external amplifier to deliver more power to your speakers and subwoofers.
- Steering wheel controls compatibility: The steering wheel controls let you operate the single DIN head unit from buttons placed on the steering wheels and perform basic operations, such as adjusting the volume or switching from radio to media player. If you want to use these controls, make sure the unit you like is compatible.
- Design: Most cutting-edge single DIN head units come with full-color displays and customizable color schemes, backlit buttons, and other interesting perks that can enhance the interior of your car.
- Anti-theft protection: The best single DIN head units come with security codes and detachable face plates as anti-theft measures.
- Remote control: Allows you to control the audio system from a distance and is useful when you’re using your car’s audio to liven up an outdoor event or to allow a backseat passenger to control the single DIN head unit.
